Advantages of High-speed Vitrified Bond CBN Grinding Wheels

Vitrified bond CBN grinding wheel has high grinding efficiency, good shape stability, high durability, finishability and other advantages, so it has become the fastest growing variety among different types of bond CBN grinding wheels. From 1980 to 1993, in the bond component ratio of CBN grinding wheel, vitrified bond increased from 4% to 37%, with a sharp rise in the trend.

For vitrified bond CBN grinding wheel under high speed rotary grinding, if people increase the feed speed and grinding depth of grinding wheel, it can significantly improve the efficiency of grinding; If it only needs to raise the speed of grinding wheel and does not increase the feed, it can improve the durability of grinding wheel, the machining accuracy and surface roughness of workpieces. High-speed vitrified bond CBN grinding wheel has the above a series of advantages, so it gets the worldwide attention, and is becoming a hot spot of abrasive products R&D in the world.

Strength, especially the tensile strength, is the key factor influencing high-speed vitrified CBN grinding wheel. If the strength is not enough, it will easily cause rotary fracture in the process of wheel grinding, which will cause the harm to people and equipment. Therefore, the force analysis on grinding wheel under high speed rotating is quite important too.
